| Additional information | Identifies the presence of serum antibodies against intercellular substance in squamous epithelium (pemphigus vulgaris) or basement membrane (bullous pemphigoid). Nuclear staining may be seen from sera of patients with systemic lupus or other connective tissue disorders. Antibodies are typically present during active disease. If positive it is advisable to perform direct immunofluorescent testing on biopsies of skin lesions. A two-fold drop in titer is indicative of effective therapy.
